Hello, I currently have an AMD fx 6300, GTX 1060, gigabyte-78lmt-s2, 1tb hard drive, and a 350-watt power supply. I am planning on upgrading my CPU to either the i5 6500 or the 6600k. I need to know which CPU is better and how big of a difference (note I do not know how to overclock). Also if my power supply is enough. According to the Coolermaster power supply calculator it is more than enough but I am not sure how correct that is. Thank you in advance. s

The difference between the two CPUs is that the 6600K can be overclocked, and has an ~8% clockspeed advantage, which should equate to ~8% more performance without overclocking. Be aware that the 6600k does not include a cooler, necessitating that you buy one.

i5 6500 ~ 65w
GTX 1060 ~ 120w
Rest of system ~ 20-40w

Total ~225w, give the power supply an extra 50% safety margin and you're up to ~335w, meaning a 350 is appropriately sized.

HOWEVER, brand and model are very important. An off-brand unit that claims 1000w may die under a 200w load a week later, destroying your PC, while a high quality 250w unit might power those components safely for a decade or more. I assume you're already using this power supply and it hasn't died yet, but...
